WILLIAM T. LEWIS, OF COLUMBUS, OHIO.

Specification of Letters Patent.

Patented July 2, 1907.

Application filed July a, 1906. Serial No- 328,304.

To all whom it may concern,

Be it known that I, WILLIAM T. LEWIS, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Means for Converting Reciprocating into Rotary Motion, of which the following is a specification.

The object of this invention is to provide a cheap and simple mechanism for converting reciprocating into rotary motion.

The invention consists in the construction hereinafter described and claimed.

In the accompanying drawings-Figure 1 is a top plan view of the mechanism as I use it; Fig. 2 is an end view looking at the lower end of what is shown in Fig. 1, some parts being in section on the line x:c Fig.1; Fig. 3 is a sectional view on the line y-y Fig. 2; Fig. 4 is a section of the rack frame alone on the line zz Fig. 1..

In the views 1 designates a bed or rest for the parts.

2 designates a stationary spindle projecting from the bed.

3 designates a guiding frame pinned.- to the end of the spindle 2, said guiding frame receiving and guid ing the rack frame 4. v

The character 5 designates a ratchet wheel having its opposite faces provided with teeth. This ratchet wheel turns on the stationary spindle 2 and has a lateral hub 5 extending to the base of the spindle. This hub 5 has keyed to it by a pin 5 a large wheel, in the instance shown a spur gear 6. This wheel 6 can be used to transmit motion or it can serve as a fly wheel for momentum.

Loosely mounted on opposite sides of the ratchet wheel 5 are spur wheels 7 and 8. The spur wheel 7 turns on the spindle 2 and the spur wheel 8 turns on the hub 5, and each is provided at its rim with a laterally-projecting spring-actuated pawl, as seen at 7 and 7 respectively, to alternately engage and slip upon the adjacent face teeth of the ratchet 5. The spur gears 7 and 8 are engaged at opposite sides by the teeth of the rack frame 4 so that when said frame has imparted to it a reciprocating motion the said spur gears are rotated and their rotating motion in the corresponding direction imparted to the ratchet 5. As an illustration of one means for imparting the reciprocating motion to the rack frame I have shown a piston rod 9 and a fraction of the cylinder 10 in which the piston of the rod is located.

11 designates a clamping piece having threaded bolts projecting from the sides thereof, said bolts passing through the bed 1 where they are provided with nuts for securing the bed if desired to some object containing the part to be operated.

What I claim and desire to secure by Letters Patent is:

1. In a machine for converting reciprocating into rotary motion, the combination of a stationary spindle, a guiding frame thereon, a ratchet wheel having its opposite sides provided with face teeth, said wheel being loosely mounted with reference to said spindle, spur gears loosely mounted on said spindle on opposite sides of the ratchet wheel and provided with laterally projecting pawls adapted to alternately engage and ride over said ratchet teeth, and a rack frame in said guiding frame to rotate said spur gears.

2. In mechanism for converting reciprocating into rotary motion, the combination of the stationary spindle, a rack-guiding frame thereon, a ratchet wheel loosely mounted thereon with reference to said spindle, said ratchet wheel having a laterally-extended hub, spur gears loosely mounted with reference to said spindle and provided with pawls adapted to alternately engage and ride over said teeth, a rack frame in said guiding frame to rock said spur gears, and a Wheel keyed to the hub of said ratchet wheel.

3. In a mechanism for converting reciprocating into rotary motion, the combination of a spindle, a ratchet wheel on said spindle having face teeth on its opposite sides, spur gears loosely mounted on said spindle on opposite sides of said ratchet wheel, laterally movable pawls on said spur gears adapted to alternately engage and slide over the face teeth of said ratchet wheel, and a rack frame to rotate said spur gears.

4. In a mechanism for converting reciprocating into rotary motion, the combination of a stationary spindle, a sleeve rotatably mounted on said spindle, a ratchet wheel fixed on said sleeve, a spur gear loosely mounted on said spindle on one side of said ratchet wheel, a second spur gear loosely mounted on said sleeve on the opposite side of said ratchet wheel, pawls on said spur gears adapted to alternately engage and slide over the teeth of said ratchet, and a rack frame to rotate said spur gears.

WILLIAM T. LEWIS.
